More than it is the detailed construction of the massager (lower leg massaging module 12 wherein) of a preferred embodiment of the present invention. when using above-mentioned massager, the shank local of user's both legs is respectively between two kneading assembly 60a, 60b of correspondence (note: between shank and mechanism, meeting is across sheet 16), and the length direction of shank is corresponding to the length direction of body frame body 20, therefore, when the first drive unit drives seat body 30 along aforementioned long shape trajectory displacement, two paired kneading assembly 60a, 60b can in inside and outside two sides of shank along shank synchronous shift. when the 2nd drive unit drive shaft 40 rotates, the first circumference portion 52 of inner side drivening piece 50a and outside drivening piece 50b can produce the eccentric and crooked motion that rotates separately, make in the first periphery, circumference portion 52 of correspondence and periodic crooked action to be produced with the inner side kneading assembly 60a that rotating shaft 40 rotates and outside kneading assembly 60b correspondence with the 2nd circumference portion 62 ring set separately, wherein, due to two paired drivening piece 50a, the axis in the first circumference portion 52 of 50b tilts to present symmetrical, so two paired kneading assembly 60a, it is axle that the rocking arm 61 of 60b can show greatly respective rear end, front end is periodically close to each other, away from, simultaneously, top side/the bottom side of two paired rocking arms 61 also can periodically simultaneously toward in, toward outer incline, make two paired kneading assembly 60a, the kneading portion 65 of 60b produces the cyclical movement that can be used for being carried out by user's shank kneading massage.

When the kneading portion 65 of two paired kneading assembly 60a, 60b is close to each other to supporting and during user's shank, endless elastomeric 64 can be complied with and compress strength and produce corresponding elasticity distortion, namely, more against user's then more flat contracting of aforementioned ellipse, compress strength with excessive resorption, avoid user to feel pain. In said structure pattern, endless elastomeric may curve with metal sheet, and block (kneading portion) is assembled on elastomerics in addition.

Before address, user can by knob 18 be adjusted to the spacing of two kneading assembly 60a, 60b in rotating shaft 40, so, shank is relatively thin or wishes that aforementioned intervals can be turned down by the user that kneading power road is stronger, makes narrower width during 65 closing of relative two kneading portions; Otherwise, shank is relatively thick or wishes that aforementioned intervals can be tuned up by the more weak user in kneading power road, makes wider width during 65 closing of relative two kneading portions. In addition, as previously mentioned, along with seat body 30 declines/rises, the spacing of two paired kneading assembly 60a, 60b in rotating shaft 40 can automatically reduce with certain speed/expand, to coordinate the shape that general human calf top is relatively thick, bottom is thinner.

While with left and right two sides of kneading assembly 60a, 60b kneading user's shank, exterior of finger 80 also can intermittently press the rear side of user's shank with same period. In details of the words, when rotating shaft 40 continues to rotate, cam part 55 can rotate with same period bias, and around about 1/2nd cycles circled, cam part 55 can by with the narrow section 57 of cam side face 56 to connecing reed 70 (as shown in Fig. 8-1), rotate into the length-diameter part 58 of cam side face 56 to connecing reed 70 (as shown in Fig. 8-2) so that exterior of finger 80 by cam part 55 by the indirect ejection of going-back position to progressive position. In other about 1/2nd cycles, cam part 55 is again by with length-diameter part 58, to connecing, reed 70 rotates into narrow section 57 to connecing reed 70, make reed 70 can revert back to flat condition because of the elastic force of self by deflected, and exterior of finger 80 is taken back going-back position by progressive position. So going round and beginning again, exterior of finger 80 can ceaselessly to-and-fro movement between progressive position and going-back position. Thus, when kneading assembly 60a, 60b to user's shank local left and right two sides carry out kneading while, the rear side of aforementioned shank local can be carried out the shuttle Shiatsu in front and back by the finger pressing section 82 of exterior of finger 80, thus expansion massage position, abundant massage content, reach and promote treatment effect and object that use sense is subject to.

In addition, the warm air that air heating apparatus 14 exports can arrive the front of exterior of finger 80 via flexible conduit (not shown), blowing forward to deliver to across ventilative sheet 16 holds in space 66, make warm air can concentrate the user's shank local being fed to and accepting massage, play preferably thermotherapy effect. Except being located at the outlet side of flexible conduit between two paired kneading assemblies, be relatively positioned at the rear side holding space, the present invention also can select to be located at outlet side near the kneading portion of kneading assembly, relatively be positioned at left side and/or the right side in accommodation space.

In above-mentioned better embodiment, by default component matching relationship, roughly go up, when the spinning movement of rotating shaft 40 drives two paired kneading assembly 60a, when 60b is close to each other by open configuration, the length-diameter part 58 of cam side face 56 can transfer front to by the rear of rotating shaft 40, exterior of finger 80 is moved forward position displacement by going-back position, otherwise, when rotating shaft 40 drives two paired kneading assembly 60a, 60b by closing state mutually away from time, the length-diameter part 58 of cam side face 56 can transfer rear to by the front of rotating shaft 40, make exterior of finger 80 move back position displacement by progressive position backward. at least, when exterior of finger 80 is positioned at progressive position, two paired kneading assembly 60a, 60b present the state of relative closing, in other words, and the opportunity of user's shank left and right two sides when the opportunity that exterior of finger 80 presses user's posterior leg coordinates kneading assembly 60a, 60b to press. in addition, the present invention is by detecting the Angle Position (note: this is prior art) of rotating shaft 40, in good time stop two motor 45 and make drivening piece 50a, the 50b in rotating shaft 40 and cam part 55 fixed only at special angle, two paired kneading assembly 60a, 60b are made to suspend the state in relative closing, and exterior of finger 80 also suspends at progressive position, thus user's shank local is carried out the long period 3 pressings of (such as half second or a second), and then allows rotating shaft 40 continue to rotate.

Certainly, cam side face in the present invention matches mode in time except above-mentioned eccentric circle, also other different shapeies or relative angle can be become according to Demand Design, exterior of finger correspondence is made to produce different motion morphologies, such as: cam side face presents avette or predetermined irregular shape, making when rotating shaft continues to rotate, exterior of finger can go to progressive position with slower speed (or negative acceleration), leave progressive position with speed faster (or positive acceleration) and/or stop in progressive position longer time; Or, cam side face presents the ellipse centered by rotating shaft core (being considered as having two length-diameter parts and two narrow section), and whenever cam part with rotating shaft from circling, exterior of finger can complete twice front-rear reciprocation movement, namely presses user twice.

In other embodiments of the invention (not shown), the unitized construction of aforementioned exterior of finger, elasticity part and cam part also can be selected to adopt following pattern: exterior of finger is being located on a body in the way of slide anteroposterior between the two positions; Elasticity part is a compression spring, and its front end is butted on a body, and rear end is butted on exterior of finger; The cam side face of cam part is directly connected to the rear side of exterior of finger, when the length-diameter part of cam side face transfer front to and exterior of finger is pushed away move forward position time, compression spring is flat contracting vertically, when the length-diameter part of cam side face transfers rear to, exterior of finger is pushed away back going-back position by the elastic force that post-equalization upheld by compression spring.

Although above-mentioned better embodiment is a kind of foot massaging machine that can massage user's shank and sole simultaneously, but the present invention also can be applicable to the massager of special massaging leg (or can be used for arm) certainly, it is possible to the lower leg massaging module being applied in massage chair or arm massage module. And, in fact also likely the massage mechanism of the present invention is made and only has a massage unit, can only massage for singlehanded or single leg every time. Should be noted that in addition, based on the upperseat concept of the present invention, two paired kneading assemblies in the middle of the present invention can be driven by rotating shaft and make its kneading portion repeatedly close, away from, in fact do not limit the structure pattern adopting above-mentioned better embodiment, for example, it similarly is the known kneading unit construction for carrying out kneading massage in No. I254632nd, TaiWan, China, M371014 patent and 201235030A patent disclosure case, also can overlap and use in the present invention.
